Proto3Optional
public bool Proto3Optional { get; set; }
If true, this is a proto3 "optional". When a proto3 field is optional, it tracks presence regardless of field type.
When proto3_optional is true, this field must be belong to a oneof to signal to old proto3 clients that presence is tracked for this field. This oneof is known as a "synthetic" oneof, and this field must be its sole member (each proto3 optional field gets its own synthetic oneof). Synthetic oneofs exist in the descriptor only, and do not generate any API. Synthetic oneofs must be ordered after all "real" oneofs.
For message fields, proto3_optional doesn't create any semantic change, since non-repeated message fields always track presence. However it still indicates the semantic detail of whether the user wrote "optional" or not. This can be useful for round-tripping the .proto file. For consistency we give message fields a synthetic oneof also, even though it is not required to track presence. This is especially important because the parser can't tell if a field is a message or an enum, so it must always create a synthetic oneof.
Proto2 optional fields do not set this flag, because they already indicate
optional with LABEL_OPTIONAL
.
Property Value | |
---|---|
Type | Description |
bool |
Type
public FieldDescriptorProto.Types.Type Type { get; set; }
If type_name is set, this need not be set. If both this and type_name are set, this must be one of TYPE_ENUM, TYPE_MESSAGE or TYPE_GROUP.
Property Value | |
---|---|
Type | Description |
FieldDescriptorProtoTypesType |
TypeName
public string TypeName { get; set; }
For message and enum types, this is the name of the type. If the name starts with a '.', it is fully-qualified. Otherwise, C++-like scoping rules are used to find the type (i.e. first the nested types within this message are searched, then within the parent, on up to the root namespace).
